I am getting the above error when I execute the following in a shell script called by Cron.
Code:
tar -cvf ${WORKING_BACKUP_ROOT}/${TAR_ARCHIVE_FILE} . >/${BACKUP_ROOT}/${ARCHIVE_LOG}
if [ $? != 0 ]
then
echo "`date` : ERROR occurred on creating tar file"
exit 1
fi
First, I thought that this error was not fatal and therefore the exit status from the tar should not be > 0.
The file I am tarring are constantly changing but I do need to capture the latest state for backup purposes. It is possible to disregard this warning and thus allow the tar command to proceed.
As a further point the tar file that is being created above is 8.2 GB are there any size limitation on the size of a tar file.
The OS system I am using is Debian
Many thanks for your help

I need archive data from some tar files. I use the command "tar xvf
filename". For about half of the files I get the error message
"tar:read error: unexpected EOF".
The number of bytes extracted comes very close to the size of the
tar file.

I would like to confirm my file.tar is been tar-ed correctly before I remove them. But I have very limited disc space to untar it.
Can I just do the listing instead of actual extract it? Can I say confirm folder integrity if the listing is sucessful without problem?

virt-tar-in
virt-tar-in(1) Virtualization Support virt-tar-in(1)NAME
virt-tar-in - Unpack a tarball into a virtual machine disk image.
SYNOPSIS
virt-tar-in -a disk.img data.tar /destination
virt-tar-in -d domain data.tar /destination
zcat data.tar.gz | virt-tar-in -d domain - /destination
WARNING
Using "virt-tar-in" on live virtual machines can be dangerous, potentially causing disk corruption. The virtual machine must be shut down
before you use this command.
DESCRIPTION
"virt-tar-in" unpacks an uncompressed tarball into a virtual machine disk image or named libvirt domain.
The first parameter is the tar file. Use "-" to read the tar file from standard input. The second parameter is the absolute target
directory to unpack into.
EXAMPLES
Upload a home directory to a guest:
virt-tar-in -d MyGuest homes.tar /home
JUST A SHELL SCRIPT WRAPPER AROUND GUESTFISH
This command is just a simple shell script wrapper around the guestfish(1) "tar-in" command. For anything more complex than a trivial
copy, you are probably better off using guestfish directly.
OPTIONS
Since the shell script just passes options straight to guestfish, read guestfish(1) to see the full list of options.
